Stem cells are modified to express an extracellular component including a tag cassette. The tag cassette can be used to detect, enrich, isolate, activate, track, deplete, or eliminate modified cells. The cells can be administered before or following differentiation into a more committed cell type.

Modified stem cells and uses thereof

Uses of expanded cord blood hematopoietic stem/progenitor cells (HSPC) are described. Examples include to reduce transplant rejection, to induce immune tolerance, to reduce total parenteral nutrition (TPN) feeding, opioid use, mucositis, and hospitalization following a medical procedure and to reduce graft versus host disease (GVHD) following an allogeneic transplant.

Uses of expanded populations of hematopoietic stem/progenitor cells

The present invention relates to methods, kits and compositions for expansion of hematopoietic stem/progenitor cells and providing hematopoietic function to human patients in need thereof. In one aspect, it relates to kits and compositions comprising a Notch agonist and an aryl hydrocarbon receptor antagonist. Also provided herein are methods for expanding the hematopoietic stem/progenitor cells using kits and compositions comprising a Notch agonist and an aryl hydrocarbon receptor antagonist. The hematopoietic stem/progenitor cells expanded using the disclosed kits, compositions and methods include human umbilical cord blood stem/progenitor cells, placental cord blood stem/progenitor cells and peripheral blood stem cells. The present invention also relates to administering hematopoietic stem/progenitor cells expanded using a combination of a Notch agonist and an aryl hydrocarbon receptor antagonist to a patient for short-term and/or long-term in vivo repopulation benefits.

Compositions and methods for enhanced generation of hematopoietic stem/progenitor cells

The present invention relates to a combination of placental stem cells and stem or progenitor cells derived from a second source, wherein the combination shows improved engraftment as compared to placental stem cells or stem cells from a second source, alone. The combination is referred to as a combined stem cell population. The invention also provides in vitro and in vivo methods for identifying and producing combined stem cell populations, and models of engraftment. In accordance with the present invention, the placental stem cells may be combined with, e.g., umbilical cord blood-derived stem or progenitor cells, fetal or neonatal stem cells or progenitor cells, adult stem cells or progenitor cells, hematopoietic stem cells or progenitor cells, stem or progenitor cells derived from bone marrow, etc.
